Hi all,
I have a SF DAC that I really like, it only accepts 44.1/48. I'm having difficulty finding a usb converter that says it can be set to "downsample". Also need to have it output over AES. Any suggestions would be appreciated.
Thanks - Rick

I doubt you will find any. Reason being, this option belongs into the playback software. Check the maximum sample rate settings in yours.

I would recommend against AES. There are some here who rant and rave about SPDIF and how you must use 75 Ohm BNC. But the impedance mismatch for BNC vs. RCA is trivial next to the AES connection on XLR. So with XLR for digital you really create huge problems.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to untolerable pain. Really, what more could we need?

I don't think so! The best sounding digital in my system comes from my Toshiba notebook computer with Windows 7 and Foobar2000 streaming to an April Music Stello U3 Link that outputs via AES/EBU to my TASCAM DA-3000 DSD recorder configured to operate as a PCM DAC. I just discovered I could use the TASCAM DA-3000 as a DAC and it sounds absolutely superb via AES/EBU. The Stello U3 Link converts PCM digital up to 24/192 and it also reclocks the data stream. I have never heard digital sound better except for DSD from a USB flash drive connected directly into the USB "A" port on the TASCAM DA-3000. Therefore, I think AES/EBU is an excellent digital interface -- the best I've ever heard.
To each his own!
Hi,
We have two issues here.
Objectively AES XLR connections with common SPDIF/AES3 receivers will usually produce more jitter than than the now also AES Recommend coaxial (as AES3id) connection.
Subjectively you prefer the AES XLR Input to Coaxial (I presume you tried both).
It would be interesting to run a J-test on either connection to see which performs better objectively. You don't happen to have an AP2 around?
If both SPDIF and AES on XLR are done to the same standards AES on XLR is worse, but no-one said they would be implemented this way.
Given what we know about the SF DAC's though, for this I would pick Coax over XLR myself. It uses the same Ultranlogue receiver module as the Audio Synthesis DAX. I found that better with Coax.

Hi Thorsten,
It is the same old problem that we keep running up against trying to compare technologies. In most cases, it is impossible to isolate the technology and duplicate everything else. Basically, all most of us can do is try it in our system and make the best guess as to why it sounds good or not. It could be the technology. It could be the execution. I could be our preference to a certain type of distortion.

As far as I know, USB to SPDIF converters don't resample.
You set your media player to send 16/44.1 to the USB converter and it will deliver 16/44 SPDIF

I would like to use a particular miniDSP device. Unfortunately it operates at 96khz, I need a USB converter anyway, so I thought I'd ask. From what I was reading on various mfr. sites, they seemed like most are I = O, but not clear if any could be set for a specific output or "down-sampling".
Thanks

As far as I know it is indeed I=O

I use a Bryston Buc-1 USB to SPDIF converter with JRiver 20. The sample rate can be set in the output format options. In addition to moving the usb to spdif converfsion outside of the dac box, the converter also allows computers to be used with "legacy" dacs that lack usb inputs. So the ability to downsample is a must.
Happy Listening.
